Fig. 6 is a detail sectional view, taken on line 6-6 in Fig. 1; and

Fig. 7 is an enlarged fragmentary elevational View detailing the manner in which the widening snowplow is pivotally secured upon the propul- 5 sion vehicle.

With respect to the drawings and the numerals of reference thereon, I0 represents a widening snowplow, and II indicates a propulsion vehicle for the plow. As disclosed, the propulsion vehicle 1o is a truck, but could be atractor, or, in fact, any type of propelled vehicle, automotive or otherwise.

The widening snowplow I0 is adapted to be mounted upon a propulsion vehicle, such as the l5 vehicle II, to be transported thereby. A frame for said widening snowplow I0 includes an upright rear wall I2, and upright, suitably spaced apart parallel side walls I3 and I4. The side walls I3 and I4 are integrally connected to the 20 rear wall I2 in any suitable and convenient manner, as by welding or riveting.

The rear wall I2 and the side walls I3 and I4 cooperate with a rotatable element I5 of the snowplow to provide, together with additional elements to be described, a snow removing or handling entity for said snowplow. Said rotatable element I5 is situated between the side walls I3 and I4, and is fixed, as at I6, upon a horizontal shaft I'I adapted to be rotated. A bear- 30 ing I8 for the horizontal shaft II is suitably and conveniently supported upon the side wall I4.

The frame of the widening snowplow is adapted to be disposed at one side of the propulsion vehicle which transports said plow. As disclosed, said frame is at the right side of the propulsion vehicle. A carrier for the plow frame includes a motor support of said widening plowv constituted as a rectilinear member I9 extending obliquely and crosswise of the propulsion vehicle and transversely of the plow frame, and integrally connected, as at 20, as by welding or otherwise, to the inner side wall I4 of said plow frame. Said carrier for the plow frame includes a girder member 2| extending longitudinauy of the pro- 45 pulsion vehicle and rearwardly from the member I9 and a girder member 22 extending transversely of said propulsion vehicle and rearwardly from said member I9. The girder members 2| and 22 are in the plane of the member I 9, are in- 50 tegral therewith, and are disposed in oblique relation to said member I9. The girder member 2I meets the member I9lat or near the midlength of said member I9, and the girder member 22 meets the member I 9 at or adjacent to 55 las 'the end thereof which is spaced from, or opposite, the plow frame. As disclosed, the girder members 2l and 22 are in right angle relation to each other. The ends of said girder members 2I and 22 which are spaced from the member I9 are integrally connected to each other.

`Said propulsion vehicle II may be of any ordinary or preferred construction. As disclosed, it includes a chassis 23 upon wheels 24 and carrying a body 25, ordinary motor 26, etc., at the forward portion of the vehicle. At the rear of the body 25, the chassis 23 includes spaced apart, horizontal, longitudinally extending vehicle frame members 21 which connect at their rear ends with a transverse rearward vehicle frame member 28. l

The transverse girder member 22 is .adapted to be detachably pivoted upon the rearward portions of both of the longitudinally extending vehicle frame members 21 in such manner that the members I9, 2I and 22 constituting the carrier for the plow frame can rest squarely upon both of said longitudinally extending frame members with said plow frame and the rotatable element I5 therein situated in proper and intended opera-y tive position at a side of and relatively to the propulsion vehicle. To this end, the rearward portion of each vehicle frame member 21 rigide ly supports a bracket 29, said brackets as shown being in proximate relation to the transverse rearward vehicle frame member 28, and each bracket 29 integrally supports one or more ears 30 disposed adjacent the transverse girder mem-1 ber 22. In turn, said girder member 22 integrally supports ears 3l complemental to the ears 39, andeach set of ears 30 and 3| is pivotally connected together, as by a rod or pin 32 which extends through the complemental ears. While the construction and arrangement as illustrated and described makes provision for supporting the widening snowplow upon the longitudinal frame members 21, the pivotal or hingedconnection between said longitudinal frame members and the snowplow makes provision for swinging said snowplow upwardly of the vehicle in any in` stance where this is desirable, as when the vehicle is to be made to travel to or from a job to be accomplished.

The rectilinear member I9 Asupports an internal combustion engine 33 of the widening snowplow which is 'adapted tothe purpose o-f driving or turning the rotatable element I5. As shown, the shaft 34 of said engine 33 rigidly supports a gear or sprocket 35. A chain or belt 36 which rides on the gear or sprocket also rid-es on a second gear or sprocket 31 fixed upon the. horizontal shaft I1. Upon operation of the engine or motor 33, the rotatable element I5 will be driven or turned through the instrumentality of the gear or sprocket 35, the chain or belt 36, the gear or sprocket 31 and the horizontal shaft I1.

The inner side wall I4 of the plow frame is closed, while the outer side wall I3 ofsaid plow frame is cut away, as at 38, to be substantially open. The plow frame and the rotatable ele` ment therein are disposed obliquely of the propulsion vehicle, slanting outwardly and rearwardly therefrom, so that the open'front of said plow frame is situated diagonally relatively to said propulsionvehicle. As shown, the cut-away portion 3B of the plow frame is generally circular, and the material of the outer lside wall I3 surrounding said cut-away portion provides, to-` gether with the rear wallV I2, inner side wall I4 and a circumferential wall 39 'of said plow fram'e extending between the margins of said side walls I3 and I4 and merging in said rear wall I2, an annular pocket or way 40 of the plow frame which is constituted as the outer part of a cylindrical passageway or slot 4I with which the open front of the outer side wall I3 communicates.

A mold board of thesnowplow includes an inner upstanding side wall 42 adjacent the forward portion of the outer side wall I3 which extends forwardly from said outer sidev wall al3 and is connected thereto, as at- 43, at location in advance of the cut-away portion 38. Said mold board also includes an outer upstanding side Wall 44 adjacent the rearward portion of said outer sidewall I3 which extends forwardly and outwardly and merges at its lower portion in a forwardly extending, downwardly and inwardly yslanting snow guiding surface 45. The upstanding side wall 44 and the snow guiding surface 45 arev disposed to the rear of the cut-away portion 38, and the lower portion of said'snow guiding surface 45 is situated below the elevation of said cut-away portion. The forward, upright edge Vof the side wall 44 includes a knife edge 46. The' snow guiding surface -45 is adapted lto the purpose of causing snow and ice to befdirected 'toward the open front of the plow frame. A lower snow guiding surface 41 of the mold yboard is disposed below the cut-away portion l38 and between the snow .guiding surfaceA 45 and the upstanding side wall 42. The lower edges of .the'snow guiding surfaces 45 and 41 provide a continuous' knife edge 48 at ground level, whichknife edge 48 meets the knife edge 46 and a knife edge 49 provided by the forward edge of the side wall 42. The inner edge of the snow guiding surface 45 merges in the outer edge of the snow guiding surface 41, and saidsnow guiding surface 44 slants upwardly and rearwardly from its knife edge 48 to the lower part of the cut-away portion 38. That is, the snow guiding surface 41 is connected to the outer side wall- I3 at a lower part of the cut-away portion 38. The union bee 'tween said outer side wall I3 and said 'snow guiding surface 41 provides a knife "edge '50. The upper portions of the walls I3, 42 vand S44 are interconnected by a downwardly and rearwardly extending wall 5I. A rearward portion `of the annular pocket or way 4l)v which is constituted as the outer part of the passagewayor slot 4I opens to an outlet passageway 52 leading from said passageway or slot 4I.v I

The rotatable element I5 includes a pair of spaced apart, parallel discplates 53 and 54 which are retained in-iixed relation to each other by a plurality of snow transporting lelements 55. As disclosed, the snow transporting elements 55 are arranged between the disc plates and are disposed radially of said disc plates.y Each snow transporting element 55 is straight in the direction of its length and is curvilinear in cross-sectionand the opposite side edges of the snow transporting elements are integrally securedto the inner surfaces of the disc plates, as by Welding or riveting.y The inner end of each snow transporting element 55 desirably may terminate in slightly spaced relation to the axis of the rotatable element I5 and the outer end of each of said snow transporting elements desirably may terminate flush with the perimeters or marginsl of the disc plates 53 and 54. Each disc plate 53 and 54 Iincludes a central opening which receives the horizontal shaft I1 upon which said disc plates are secured. 4

The disc plates 53 and 54 ofthe rotatable elebetween each working ment I are arranged concentrically of and in comparatively close proximity to the circumferential wall 39. A portion of the diameter or width' of said'rotatable element l5 is within the outlet passageway52.

The inner disc plate 54 is disposed in parallel relation and close-proximity to the inner side wall I4 of the plow frame, and the outer disc plate 53 is disposed in parallel and slightly spaced relation to the outer side wall I3. The disc plate 53 carries a series of working blades orshovels 56 at the outer side of the periphery of .said disc plate.

Each working blade or shovel 56 extends more or less radially ofthe Vdisc plate 53, withits width arranged transversely of the snowplow frame. Also, each working blade or shovel 56 is curved in the direction of its width and is straight in the direction of its length. In general outline the working bladesl or shovels 56 are rectilinear, and the outer vor working end of each of said blades or shovels includes an element 51 thereof providing a knife edge 58. Desirably, a side edge 59 of each working blade or shovel is a knife edge.

Each working blade orl shovelr56 is adapted to be bolted, as at 60, or otherwise secured, up against the outer surface of the'disc plate 53 at the rear of an opening-6|, rectangular as shown, through said disc plate 53 and directly in advance of a snow transporting element 55. That is, there is a working blade or shovel corresponding to each snow transporting element 55 and an opening 6I affording communication bladev or shovel'and its corresponding snow transporting element. Each working blade or shovel 56 has one of its side edges tted to the disc plate 53 just to the rear of an opening 6I and its cutting side edge 59 arranged in spaced relation to said disc plate 53, so that the working blades or shovels in effect constitute scoops for snow. The knife edge 58 of each element 51 is adapted `to travel in close proximity to the knife edge 50, and the arrangement is such that said knife edges 50 and 58 cooperate to cause Asnow and ice to be cut or severed. The working blades or shovels 56 are adapted to wipe through a space 62 between the disc plate 53 and the outer side wall I3 of the snowplow frame when the rotatable element I5 is in operation.

Said rotatable element I5 is revolved so that its forward portion moves downwardly and its lower portion moves rearwardly, in the direction of the arrow in Fig. 2. Each working blade or shovel 56 has its outer knife edge 58 arranged immediately above the knife edge 50, somewhat within the perimeter of the rotatable element I5. The length of each working blade or shovel is such that the inner end thereof terminates a considerable distance inwardly of said perimeter. The inner end of each snow transporting element 55 and the inner end of each opening 6I may terminate about flush with the'inner end of each working blade or shovel 56.' As shown, the outer end Aof each opening 6I terminates at about the location of the corresponding element 51. The width of each working blade or shovel 56 substantially equal -to the width of the space`62. The arrangement is such that the concave surfaces of the working blades o-r shovels 56 and the snow transporting elements 55 are the working and the transporting sur'- faces, respectively, thereof. The outer ends o-r edges 58 ofthe working blades or Vshovels 56 rotate in close proximity to the knife edge l50, and the outer endsl or edges of the snow transporting elements 55 rotate in close proximity to the circumferential wall 39. The spaces between the disc plates 53 and 54 and definedby said disc plates `and the snow transporting elements 55 are open at their outer portions. A-

The manner in which the rotatable element I5, including the disc plates 53 and 54 with snow transporting elements55 and working blades or shovels 56, operate will be evident. The surfaces 45 and 41 of the mold board cooperate to life the snow and ice severed or cut from the ground by the knife edge 48 and direct the snow and ice into the space 62 of the passageway or slot 4I. Each working blade or shovel 56 cooperates with the disc plate 53 and with the adjacent, outer side wall I3 of the plow frame to cause snow and ice to be carried through the corresponding opening 6I into the space between the disc plates 53 and 54 in front of a snow transporting element 55, and each snow .transporting element 55 carries an` individual load or shovel-full of snow up through the outlet passageway 52. The disc plates 53 and 54 rotate at high rate of speed, andthe snow and ice leaves the outlet passageway 52 in the form of individual and separate charges of snow and ice each equal in amount to a shovel-full of snow and ice forced out of the machine under considerable momentumby the centrifugal force exerted through the working blades or shovels 56 and the snow transporting elements 55. Said working blades or shovels keep wiping through theV space 62 of the `snow passageway or slot 4|, and the cooperating arrangement among the working blades or shovels, openings 6I, snow transporting elements 55, disc plates 53 and 54 and the walls of the plow frame defining said passageway or slot 4I is. such that snow and ice once upon a workingblade or shovel will be quickly forced or carried out ofl the machine by a corresponding snow transporting element 55. There is noopportunity for snow and ice when once upon a working blade or shovel or a snow transporting element to fall backwardly of the working blades or shovels or the snow transporting elements. l

The working blades or shovels 56 and the openings 6I can obviously have relation to the snow transporting elements 55 to provide snow receiving spaces between the disc plates 53 and 54 and forwardly of said snow transporting'elements of any size selected as satisfactory. As shown, each snow transporting element 55 and its corresponding working blade or shovel 56 are parallel. Desirably, the snow transporting elements will be disposed radially of the disc plates, but'the working blades or shovels' may be out of parallel with said snow transporting elements. The working blades or shovels 56 may be set at a sharper angle to snow and ice than as disclosed, thus better to remove or handle the snow and ice.

It will be seen that the snow and ice is dislodged by the working blades or shovels56 at location inwardly of the perimeter of the rotatable element I5, while dislodged snow and ice is propelled from the outer ends of the snow transporting elements 55 at the perimeter of said rotatable element. The working blades or shovels are of inexpensive construction, are easily replaceable, and have great Strength. Each blade or shovel is. bolted to the disc plate 53 independently of all others of the blades or shovels. The snow transporting elements are subjected to no .suchl hard; labor as is required of the Working bladesA or shovels and ,are not liable to become broken under. any, even .the severest, conditions of `.use of the machine.

Mechanism for. elevatingand lowering .the 'snowplow is `denoted generally at 63.V As shown, said mechanism ismounted upon and at the midlength of a basev member 64 extending transversely of and supported by vthelongitudinally lextending frame vmembers. 21 of the propulsion vehicle. Awmember. to be actuated by. the mechanismfS is secured to and extends forwardly from the rectilinear member I9 of the carrier for the'iplow frame." The .actuated member 65 is between and yat equal distance from the longitudinally extending frame .members 21, and meets the base' member 64 at its midlength. Thus, the snowplow is not only squarely supported upon both longitudinally extending frame `members-of the chassis of the propulsion vehicle when in 'lowered position, butis also squarely d'supported upon both longitudinal frame members when in .elevated position.

f The snowplow-illustrated in the drawings and hereinbefore described isfmore especially useful as a widening snowplowj. that is, the propulsion vehic1ewill transport the snowplow over aV surface or roadway which may havebeen partially cleared of snow, and ysaidsnovvploy will causel snow to .be removed "aiong "aline Vparallel to a cleared or partially cleared strip yof roadway to Widen said vcleared or partially cleared strip, as will be understood. The widening snowplow can be supported upon the :propulsion vehicle to be :nearer to y-or .farther away from the ground.

The rotatable 'element f5v will vbendrlven whenever the engine shaft 34is in operation. Desirably, there 'will be included as apart of the drive connection between the yengine shaft andv vthe rotatable element,` amember of less strength than is any part of said rotatable elemenaso that when an obstruction causes breakage, this breakage will disconnect sai-d engine shaft tilly from the rotatable element I5. y The Vconstruction vand `arrangement as =illustrated `and describedrmakes provision for conveniently supportingI the snowplow and its appurtenances clear nof the parts of the propulsion vehicle., vMore explicitly, V'said' construction and .arrangement causesithe motor 33 to bein spaced relation to the transmission mechanism Yof said 'propulsion vehicle rearwardly thereof and the 1 snowplowkframe to be in spaced relation to the I right rear wheel ,forwardly thereof.
